/**
 * This class is the result of countless discussions of what
 * a Category should be. After determing that it should be
 * another class, and that we can do something useful, we
 * created this Category.

 * A Category is a logical extension of the Configuration
 * has Categories has Properties has Value frame-of-mind.
 * The primary goal is to reduce redundancy in source code
 * when using setter and getters that include Category
 * information.
